Allen-Bradley 1606-XLERED | Power Supply Redundancy Module

Product Overview

The 1606-XLERED is a redundancy module from the Allen-Bradley Bulletin 1606 series, designed to maintain continuous operation in critical automation systems. It ensures uninterrupted power delivery by enabling 1+1 or N+1 redundancy configurations, where an additional power supply remains on standby to take over instantly if one unit fails.

Technical Specifications

The 1606-XLERED supports a maximum current rating of 20 Amps and total output power of 480 Watts. Its typical output voltage operates at 1 or 0.9 Volts, depending on system requirements. This module functions without steady-state input current support, which highlights its specialized design for redundancy applications.

Power and Connections

This redundancy module integrates advanced MOSFET or diode isolation to prevent backfeed between power supplies. It requires no auxiliary voltage, even during short-circuit conditions at the output. The device includes special terminals and a DC-OK signal function, allowing engineers to monitor system status easily and ensure reliable performance.

Design and Efficiency

With its compact size, the 1606-XLERED allows efficient panel integration without consuming excessive space. Its switched-mode design minimizes heat generation, improving energy efficiency and extending component lifespan. The adjustable output voltage offers flexibility for diverse industrial installations.

Application Benefits

The 1606-XLERED is ideal for automation environments that demand constant uptime, such as process control, manufacturing, and critical facility operations. By maintaining isolation between each connected power supply, it guarantees stable and fault-tolerant power distribution, safeguarding system reliability.
